Currently, sealing glue is usually used at the lap joint edge during construction, or a weather-resistant butyl tape is added to assist in sealing the lap joint edge to achieve waterproofing while being exposed to use.

[0027] The preferred embodiments of the utility model will be described in more detail below. Although the preferred embodiments of the utility model are described below, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to make the utility model more thorough and complete, and to fully convey the scope of the utility model to those skilled in the art.

[0028] The utility model provides a kind of modified asphalt waterproof coiled material which can be used externally, comprising:

[0029] Isolation film, cover in the lower layer of modified asphalt layer, the overlap edge of the upper layer of modified asphalt layer is covered with isolation edge film;

[0030] The other surface of the upper layer of modified asphalt layer is covered with weather-resistant film or weather-resistant composite film, and the length of the weather-resistant film or weather-resistant composite film extends outside the modified asphalt layer.

[0031] Specifically, the weather-resistant film or weather-resistant composite film of the upper layer of modified asphalt layer is extended outward by some length, and when the adjacent two layers of asphalt waterproof coiled material are overlapped and laid, the lower layer of the upper modified asphalt layer can be completely covered on the exposed surface of the lower modified asphalt layer with the isolation edge film torn off, or the lower layer of the upper modified asphalt layer and the extended part of the weather-resistant film or weather-resistant composite film can be covered on the exposed surface of the lower modified asphalt layer with the isolation edge film torn off. In this way, the overlapped part of the upper and lower waterproof coiled material can be waterproofed by the extended weather-resistant film or weather-resistant composite film, avoiding long-term contact with the external environment, affecting the bonding difficulty, and using the waterproof coiled material for laying can achieve higher weather resistance life, improve the convenience of construction and reduce the use of raw materials.

[0032] Optionally, the weather-resistant film is a weather-resistant PE film, a weather-resistant PET film or an aluminum foil film, and the thickness of the weather-resistant film is 10 μm to 200 μm.

[0033] Specifically, when a weather-resistant film is selected to cover the upper layer of the modified asphalt layer, the weather-resistant film is a film with weather-resistant properties, which can be a weather-resistant PE film, a weather-resistant PET film, or an aluminum foil film. The color can be white, silver, blue or other colors, with a thickness of 10μm to 200μm and a width of 900-1020mm.

[0034] Optionally, the weather-resistant composite film is a weather-resistant composite film of a polymer film and an aluminum foil film or a weather-resistant composite film of a polymer film and a polymer film, and the thickness of the weather-resistant composite film is 20-200 μm.

[0036] At present, when exposed roll materials on the market are being constructed, the overlapping edges of adjacent roll materials are weak points in terms of resistance to natural aging, and sealants or an additional layer of weather-resistant butyl tape are often used to assist in sealing the overlapping edges. However, in the present application, the length of the weather-resistant membrane or weather-resistant composite membrane is set longer, so that the weather-resistant membrane or weather-resistant composite membrane extends beyond the modified asphalt layer. In this way, when overlapping with adjacent roll materials during construction, the excess portion covers the overlapping edges, thereby avoiding natural aging caused by the exposure of the overlapping edges. Compared with the construction of existing exposed roll materials, this waterproof roll material eliminates the need for auxiliary sealing sealants or butyl tapes, which not only reduces the construction volume but also reduces the cost of construction raw materials.

[0040] Optionally, a reinforcing membrane is provided in the middle of the modified asphalt layer. The reinforcing membrane is a polymer membrane or a polymer composite membrane. The thickness of the carcass membrane is 10-200 μm.

[0041] Specifically, the polymer carcass membrane is a common commercially available polymer membrane, which may be a PET film, a PE film, a PE cross film or other polymer membrane or a polymer composite membrane, with a thickness of 10-200 μm and a width of 900-1000 mm.

[0042] Optionally, the isolation membrane and the isolation edge membrane are made of the same material.

[0043] Optionally, the material of the modified asphalt layer is self-adhesive modified asphalt, the isolation film and the isolation edge film are PET film or PE film, and the thickness of the isolation film and the isolation edge film is 10-50 μm.
